Claims

[Claims for Utility Model Registration] While forming internal teeth having a predetermined number of teeth on the arm plate fixed to the seat back frame,
At least one tooth is engaged with internal teeth formed on the arm plate between the base plate fixed to the seat cushion frame and the arm plate, and the number of teeth is one less than the number of internal teeth. In a configuration in which a disk plate on which external teeth are formed is rotatably supported via an eccentric shaft, an elastic force is applied between the disk plate and the base plate to rotate the disk plate forward. When the return spring is installed, an elastic force is applied between the disc plate and the arm plate that causes the arm plate to rotate rearward, resulting in a gap created between the external teeth and the internal teeth during meshing. A vehicle reclining device characterized by being equipped with a rocking absorption spring that prevents rattling.
